Rail Neutral Temperature Monitoring for Rail Transit

The project will further develop and test unique Intelligent Rail Integrity System (IRIS) to determine the conditions leading to changes in Rail Neutral Monitoring Temperature (RNT), and provide the means to continuously monitor RNT in critical curve and abutment locations, to measure this effect, and communicate the condition to an IRIS website for remote access. This program will result in safer rail transit operations by more definitive continuous reporting of rail conditions and allow for verification of field welds, distressing curves, and any rail cuts. Continuous welded rail at curves and at abutments experience changes in rail neutral temperature (RNT) over time as stiff supports inhibit redistribution and equalization of longitudinal rail force. Significant changes in neutral temperature contribute to rail buckling and derailments. The Maryland Transit Administration (MTA) will be participating with staff, equipment and facility for testing on their transit facilities. The project will be performed in the following two contingent stages. Stage I- Program Initiation and Stage II- System Implementation.
